Considering algebras in the wider sense to include coalgebras, bialgebras and similar algebraic structures such as the Drinfel’d algebras encountered in the theory of quantum groups, one can model such objects as models for an algebraic theory much in the sense of F. W. Lawvere [Proc. Natl. Acad. Sci. USA 50, 869-872 (1963)]. Individual algebras are then determined by their structural constants and hence may be amenable to a deformation theoretic approach for determining their stability under change of these constants.
